Who is The Saddest Man on Earth? We have discovered it is not the lost man, but the saved man that chooses to live as the lost man: restless as the sea (Isaiah 57:20-21). There are many of God’s people who trust Christ with their eternal soul but do not trust Him with their lives. They choose not to live in the rest that can only be found in the presence of Christ. They make a poor substitution that costs them true joy and soul rest.
